Ann, in your original post, I did not understand that you were trying to play sequenced files. You can not play sequenced files from a KN1000 into a KN7000. You would have to put them into a KN2000 and they would have to be corrected sound wise. From what I understand, you could then put them in the KN7000 but they would also require correcting. I think you are wasting your time considering this unless you are very experienced in doing this. Trying to bring up any sequenced song done in a KN1000 will not be in the KN7000 when loaded.
